21st century astrophysics is by nature interdisciplinary. Astronomers today work in collaboration and/or use methods developed by computer scientists, chemists, engineers, planetary scientists, mathematicians, etc. to address the most interesting questions about our Universe. The most innovative approaches stem from these interdisciplinary collaborations. Our REU program provides students the opportunity to pursue an astrophysics-based interdisciplinary research project in collaboration with Northwestern University faculty in Astronomy, Applied Math, Chemistry, Earth and Planetary Science (EPS), Electrical Engineering and Computer Science (CS), and/or Physics. We highly value diversity. Women, members of under-represented groups (including ethnic, racial and gender), and students
